Feature Flags

[features]
# Aggregate: pure-Rust no-ORT base + excel + OCR + tract layout/orientation.
# RT-DETR layout detection and PP-LCNet document-orientation run in WASM through
# the pure-Rust `tract` engine (layout-tract + auto-rotate-tract); weights are
# streamed in via load_from_memory (detectLayout / detectOrientation). Deliberately
# NO tree-sitter — the 306-language grammar pack pushes the browser .wasm past
# jsDelivr's 50 MB per-file cap, so code intelligence is unavailable in WASM.
